Thank you, Mark Isherwood, for your questions, and I hope you will back my call for a meeting with the Secretary of State. Of course, I have written to the Secretary of State and I have had a response from the energy Minister. I think what is very clear is that we've got to recognise the scale of this: 200,000 households in Wales use prepayment meters for their mains gas and electricity; 15 per cent of all households, 24 per cent of tenants in the private rented sector, and almost half of social housing tenants use prepayment meters, and they're on the lowest incomes. We are talking about those who are most vulnerable.

What I've said to the UK Government is that, yes, we're pleased to see energy suppliers halting the practice of forced installation, but what did it take? It took the investigation of The Times, and politicians like Jack Sargeant, and indeed Ed Miliband, I would say, to expose what was going on. Enforcement didn't work. The UK Government isn't acting enough to look at the new legislation that probably needs to come forward. There is a lack of Ofgem safeguards in place. I said to Ofgem, 'We will support you if you need more regulatory power; we need to support you to do this.'

We have to await the outcome of that investigation into British Gas. I've met with energy suppliers on a number of occasions. They've given me assurances about the way they're treating and supporting vulnerable customers. I find it very hard to actually take on board some of the assurances they've given me when we hear particularly of their use of these unscrupulous debt collection agencies. I am meeting the Enforcement Conduct Board next week, and I will be able to report back on that, because we need to look at their work. I was glad that that was raised yesterday by Peredur in terms of their use and in terms of looking at how accredited enforcement agents are key to this. I will certainly be responding to and updating the Senedd on these issues.
